Parasitic: One benefits at the expense of another
Mutualism: Organisms benefit off each other

The two types of graphs showing evolutionary change called and what are some differences?
What are...
Phyletic Gradualism: how we normally think of evolutionary change, slow/gradual changes, ex. hominids, gradient-like.
Punctuated Equilibrium: long periods of little change interrupted by speciation events, many different species from one common ancestor.
An example of a type 2 organism: high birth rate, steady death rate, predictable
At least one thing needed to meet the evolutionary adaptation criteria
What are being genetically passed down to the next generation (heritable), Be functional for a specific environmental factor (fits a niche), contribute to an advantage for that species (fitness)?
The oldest widely recognized hominid skeleton found is a specimen
